Testing for Soil Compaction:
- Use a Soil Probe
- Low-Tech: Use a wire-flag
- How deep can you push it into the ground?
- How much resistance?
- Is the soil hard, rocky, soft, grainy?

13. How to Make Compacted Soils in 30 minutes or less:
1. Drive on it with a heavy, wheeled loader.
2. Increase effectiveness by doing this when its wet

(Reduce Runoff through Stormwater Infiltration)
- Shallow (4” to 12”max. deep) Depressions
- Surface should be dry in 48 hours (or less)
- Soil amendments sometimes needed (compost and/or sand)
- Planted with deep-rooting Plants (natives work well)
- Design as a Landscape Feature (“natural”, formal, or in-between)
- Design to Integrate into Landscaping
- Select plants to attract Wildlife (for multiple benefits)
